Yet Another
Proof Problem Based on Chapter 3
This 2-column proof is a little harder, but I
think you can still do it. At the end, there is a difficult “ultra bonus” proof
that you should probably ignore for now.

Ð2 @ Ð3 WV = 2WZ |

ULTRA BONUS: Prove that Ð6 is uniquely determined by
the givens, and compute mÐ6 to the nearest ten-thousandth.
(Warning: The Ultra Bonus requires skills
from both trigonometry and precalculus. Clearly, this
is not a suitable problem for most Third Formers. However, the first student of
mine who can solve the Ultra Bonus before Memorial Day, 2005, will earn enough
ultra bonus points to make the exercise worthwhile, provided he can defend the
solution in front of me in an oral examination.)
